Nonsuicidal self-injury (NSSI) is associated with reduced pain sensitivity (PS). Existing theories posit that altered PS is a risk factor for NSSI. Cross-sectional data suggest that PS normalizes in those terminating self-injury. However, previously no study addressed the longitudinal course of PS in patients engaging in NSSI. We addressed changes in PS and clinical symptomatology in adolescents with NSSI (n = 18) and matched controls (n = 19) over one year. Despite significant clinical improvements, PS did not change in the NSSI group but decreased in controls. Greater NSSI reduction was associated with increased pain tolerance. Findings are discussed in the light of current theories on PS in NSSI.
非自杀性自伤（NSSI）与疼痛敏感性（PS）降低有关。现有理论认为，PS改变是NSSI的一个风险因素。横断面数据表明，停止自伤行为的人的PS恢复正常。然而，此前尚无研究探讨参与NSSI的患者PS的纵向变化过程。我们研究了18名患有NSSI的青少年和19名匹配的对照组在一年时间里PS和临床症状的变化。尽管临床症状有显著改善，但NSSI组的PS没有变化，而对照组的PS有所下降。NSSI减少得越多，疼痛耐受性越高。我们根据当前关于NSSI中PS的理论对研究结果进行了讨论。
